Suppose there is a switch on the wall that is inconvenient or unsuitable for us. Instead, we install a receiver for the radio switch (DJ-01i) and mount a radio-controlled transmitter (DJ-01s) on the wall or furniture. Now, using the transmitter, we can control the lighting from a new location. Used products: one set of RJ-314 radio switches. In a hallway or at the beginning of a staircase, there may be only one switch. To avoid returning to turn off the light, an additional switch can be installed. The existing simple switch is removed, and the radio switch receiver (DJ-01i) is installed in its place. Above this receiver, a radio switch transmitter (DJ-01s) is installed. An additional transmitter (DJ-01s) is mounted at the desired new location. Used products: one set of RJ-314 radio switches plus an additional DJ-01s transmitter.
